Framerates, Interlace vs Progressive and Pan Speed
If you have a lot of motion in your scenes it is always preferable to shoot progressive frame rates
instead of interlaced with S3D. This will prevent the "tearing" and temporal disparity common with
interlaced motion. Higher frame rates will improve your audience's ability to see the 3D.
However, you should also slow your pan and tilt speed down to half what you would normally use in
2D. It is more difficult to view panning shots in 3D and still fuse the objects.
Lens & Focal Length considerations
Wider focal lengths will be easier to shoot with for the beginner and will also lend more
"dimensionality" to your subjects. Telephoto lenses will force you to use smaller interaxial distances
to maintain a viewable parallax budget and therefore compress your subjects at so they appear as
cardboard cutouts. Stay away from " sheye" lens adapters because the distortion will cause many
geometrical disparities. Shooting in the zoom range of 4.1mm to 10mm with the XF-series cameras
is recommended for beginners.
SECTION 2: SHOOTING 3D WITH PAIRS OF XF105 OR XF305
This section describes the technical intricacies of con guring a pair of XF105 or a pair of
XF305 cameras (with rmware v1.0.2.0 or newer) to work together to capture perfectly
synchronized stereo3D. The following instructions will apply to either camera model unless
otherwise speci ed.
CONNECTIONS
Genlock & Timecode slave
The XF105 and XF305 cameras are
desirable for the ability to genlock to a
common reference signal and also copy
their timecode using dedicated
terminals. Timecode sync is possible
with both the XF105 and XF305
cameras but the syncing procedures
differ slightly. The XF105 shares the
GENLOCK connector with TIMECODE IN/
OUT so only one type of signal can be
connected at a time.
